title: Emergency department bedside ultrasound diagnosis of retinoblastoma in a child.
abstract: A 30-month-old boy presented to a Haitian emergency department with proptosis, periorbital edema, and progressive blindness. Bedside ultrasound examination revealed bilateral ocular masses with dense calcifications pathognomonic for retinoblastoma. This case illustrates the diagnostic utility of bedside ultrasound for an advanced case of retinoblastoma in a resource-poor setting. Ocular ultrasound technique is also reviewed.
